How is it possible to get live 4K video from the Moon? This is the secret of NASA technology
NASA has succeeded in establishing a system that enables the transmission of 4K video directly from the Moon in real-time. The astronauts of the Artemis II mission will use a state-of-the-art laser link for tens of millions of people to follow their flight live. This technological leap enables the top-quality image that we will watch on platforms like YouTube and Netflix.
TL;DR
- NASA can now transmit 4K video live from the Moon in real-time.
- The Artemis II mission will utilize a cutting-edge laser link for this purpose.
- The system uses infrared light (O2O) instead of microwaves, achieving a speed of 260 megabits per second.
- The laser devices are smaller and lighter than previous equipment.
- Up to 28 cameras on the Orion spacecraft can send video, photos, and voice messages simultaneously with minimal delay.
- The signal delay is only one second, making it nearly imperceptible to viewers.
- A significant challenge is accurately directing the laser to Earth from over 380,000 kilometers away.
- The system employs a special telescope that adapts to temperature changes in space.
- A 45-minute signal interruption will occur when the spacecraft passes behind the dark side of the Moon.
- This technology paves the way for future remote control of robots and continuous monitoring of lunar bases.
